摘要
吉林省浑江市幅1∶50000水系沉积物测量共采集1961件水系沉积物样品,采样粒级为–10目^+80目,平均采样密度为5.1个/km2。采用发射光谱法(AES)、泡沫塑料吸附石墨炉原子吸收分光光谱法(GFAAS)、原子荧光法(AFS)及等离子体质谱法(ICP–MS)分析了Au、Ag、Cu、Pb、Zn、As、Sb、Bi、Hg、W、Sn、Mo、Cd、Co、Cr、Ni等16种元素,形成吉林省1∶50000浑江市幅水系沉积物测量原始数据集。数据集包含有1961件样品以及其16元素的原始数据表1个(Excel),MapGIS格式图集1套(含有1张矿产地质图、1张采样点位图、16张单元素地球化学图、16张单元素异常图)。通过本数据集新发现单元素地球化学异常403处,综合异常24处,结合地质、物探、化探、遥感及已有成矿线索圈定金矿找矿靶区3处、铜及多金属找矿靶区2处。本文数据集为该区域提供了一套基础性的数据资源,为基础地质及其他领域应用提供基础地球化学依据。
During the 1∶50000 stream sediment survey of Hunjiang City map-sheet,Jilin Province,a total of 1961 samples of stream sediments were collected,with the sample grain size ranging from–10 meshes to+80 meshes and average sampling density of 5.1 samples per km2.Sixteen elements,namely Au,Ag,Cu,Pb,Zn,As,Sb,Bi,Hg,W,Sn,Mo,Cd,Co,Cr and Ni,were analyzed using the techniques of atomic emission spectrometry(AES),adsorption of foam plastic by graphite furnace atomic absorption spectrometry(GFAAS),atomic fluorescence spectroscopy(AFS),and inductively coupled plasma mass spectrometry(ICPMS),forming the primary dataset of 1∶50000 stream sediment survey of Hunjiang City mapsheet,Jilin Province(also referred to as the Dataset).The Dataset consists of one primary data table in Excel and a set of atlas in MapGIS format.The former is comprised of the primary analysis data of 16 elements for 1961 samples,and the later includes one mineral geological map,one sampling point bitmap,16 single-element geochemical maps,and 16 single-element anomaly maps.On the basis of the Dataset,403 single-element geochemical anomalies and 24 integrated anomalies were newly discovered.Meanwhile,three prospecting target areas of gold deposits and two of copper and polymetallic deposits were delineated based on the geological survey,geophysical and geochemical exploration,remote sensing data and existing metallogenic clues.The Dataset provides fundamental data for the map-sheet area and serves as a geochemical basis for geological research and applications in other fields.
